Dynamic temperature adjustment by real Print Speed



  • Hello

    i have a Delta Printer. I can set the Printing speed to 120 mm/s but often only 60 mm/s are used for printing when the object to be printed is small or or has an unfavorable shape.

    I am still a beginner at 3D printing which surprised me:

    Certain filament types require a different temperature at a different speed.
    But if I don't know when setting the temperature how high the real printing speed will be, everything doesn't fit.

    Is there a function in the Duet Wifi firmware that adjusts the temperature based on the real print speed ?

    Otherwise this would be a new idea for future versions.

    I know that a temperature change takes time.
    But maybe you can at least introduce some flexible printing temperatures.

    The board firmware could recognize that a desired speed is not possible at all in some areas and readjust accordingly.
    Maybe on previously defined temperature values.

    What do you think of that?

    That could be implemented, but for it to be useful you would need to calibrate the optimum temperature at different print speeds. You would still need to set a temperature in the slicer, and the firmware would increase that when it saw printing moves that exceed some predefined speed.



  • That's possible. What do you think of that ?

    I think before that I should implement feedforward in the heating system, so that when extrusion rate increases the heating power is automatically increased to compensate, to avoid a temporary drop in temperature.
